$#li@?of 6 men moved in 4 March to install air-conditioningand technical equipment. This work was ftiished Saturday, 13 March. Two members Of this group re~ined be~d in Order to Setice and maintain the equip- ment, In order to have the inside electricalwiring of all structures finished before the main body of scientists arrived, this work was given first priority and rushed to completion byls March, except for the wiring inside the Zero Tower cab which was done by two electricians of the A= group from Los Alamos. In accordancewith paragraph 2c, Change Order No. 2, beach sand was hauled and spread along a strip 100 ft. wide, extending from the 4COft. station to @mna Station C. Nine thousand cu. yds. of sand were hauled in this operation which began on 8 Msrch and extended over a period of IA days. After the sand was in place, it was decided that an area of 100,000 sq. ft. around Gamnm Stations A and B should be stabilized,using the soil cemat method, (see Change Order No. A, par 2b) in an attempt to control the dust that would rise after the blast. Outside power distributionwires were placed around the Timing Station, Gamna Station B and blast building, Monday, 8 Mrch, under the direction of Dr. Clark and Mr. Hedberg of AEC. This proved to be a very simple task as care was taken to label each wire as it was placed. All other outside wiring and floodlight installationswere finished during the week ending 13 March. Most of the week ending 20 March was spent removing excess supplies from three 40 ft x 100 ft quonset huts on the north end of the island Section XVI
